RAILWAY SIGNALING APPARATUS FOR USE IN FOGGY OR OTHER WEATHER.

Specification of Letters Patent.

Patented Feb. 26, 1907.

Application filed September 10, 1906. Serial No. 334,031,

To all whom it may concern:

Be it known that I, JOHN PARKER, a subj ect of the King of Great Britainand Ireland, and a resident of 27 Agnew road, Honor Oak Park, in thecounty of London, England, have invented certain new and usefulImprovements in Railway Signaling Apparatus for Use in Foggy or otherWeather, of which the following is a specification.

This invention of improvements in railway signaling apparatus for use infoggy or other weather, has for its object to produce a simple eflicientapparatus such that the signalman or fogman can place a detonator uponthe rail, so as to be exploded by the wheels of a passing train when thesignal is at danger or to remove the detonator from the line when clearor after the detonator has exploded.

The said invention consists, essentially, of a suitable magazine orholder for the cartridges or detonators and in connection,

therewith a projector or carrier for taking the detonators therefrom'and placing and retaining the same on the line ready for use. Theprojector or carrier preferably takes the form of a hollow tube carriedby a rod and suitably guided, so as to slide and carry the detonatorsone at a time from the magazine. This sliding tube, with the detonatorsor cartridges carried thereby, is operated by the signalman or fogmanthrough a suitable arrangement of levers, rods, cranks, or equiva lentmeans, so that when the signal is at danger a detonator can be placedand retained on the line ready for exploding, or when the line is clearit can be removed therefrom and kept in position ready for use, or,again, it can be withdrawn from the rail when exploded and the emptycase ejected from it and a fresh one taken from the magazine, thesliding tube, projector, or carrier being cut away for a portion of itslength to permit of this charging and recharging of the detonators,while the gripping of the detonators is effected by the end of saidsliding tube or carrier in such a way that the detonator is rigidly heldin said tube, so that it cannot be shaken out of position either when inthe tube or placed upon the rail.

In order that the said invention may be readily understood, reference isto be had to the further following description and accompanying sheetsof drawings, in which-- Figure 1 is a side elevation of the appara- Fig.2 is an end view thereof. Fig. 3 is a side elevation with inclosingcasing partly in section; Fig. 4, a sectional elevation, casing removed,showing projector or carrier receiving a cartridge or detonator; Fig. 5,a similar view showing projector drawn back to fix cartridge therein;Fig. 6, a similar view showing projector fully extended, cartridge onrail Fig. 7, a vertical section on line :2 a: of Fig. 5; Fig. 8, a planview of Fig. 5, magazine leing removed; Fig. 9, a plan view of themagazine cover, partly broken away; Fig. 10, a section on line y y, Fig.9.

Like letters of reference indicate corresponding parts in the severalviews.

Referring to the drawings, a, Figs. 1 to 8, represents a base-plateprovided with standards b b, in which are housed the parallel guide-barsc c. Centrally located of said guide-b are c c and screwed at d in thestand ard b (for adjustment purposes) is the bar d, upon which isadapted to slide the hollow projector or carrier 6, movement beingimparted thereto through the head 0, carried on the guides c c by meansof the swinging link e connected up to any suitable arrangement oflevers or equivalent devices operated from the signal-box or by thefogman.

The projector or carrier 0 is provided at its front end with an openingor slot 6 Figs. 4, 5, 6, and 8, for the purpose of receiving (see Fig.4) a detonator or cartridge f from the magazine g, which is attached byhooks g g at its forward end to the distance-piece g on the front rod 0,(see Fig. 7,) the underneath p art of said magazine resting on the otherrod 0 and, if necessary, supported, as shown in. Fig. 2, by a stay 9 thedetonators rolling down the magazine under their own weight and that ofthe rolling weight f, Figs. 7 and 9. For the purpose of keeping theworking parts and contents of magazine dry the same is inoased, as shownin Figs. 1 to 8 and 7 to 10, the magazine being provided with a hingedlid 9 adapted when said magazine is in position to be locked to thecasing 7L, sur rounding thesignaling apparatus, said casing it beingprovided with a cover h, adapted to be locked out of the way when themagazine is in position or to be looked over the opening left on theIGIT.OVLl of the magazine. Furi ther, the top of the casing h is pivotedat k so that it may be swung upward for cleaning and other purposes.

In use the magazine 9 (charged beforehand, if desired) is placed inposition, as shown, communicating by its opening 9 Figs. 7 and 9, with achamber 9, connected to the standard I) by the distance-pieces g 9*,Fig. 8, and guides 9 between which fits the magazine. The projector orcarrier e is now moved forward, so that its slot 6 is beneath theopening g of the magazine, permitting a detonator to fall. (See Fig. 4.)The projector or carrier is now moved back to the end of its stroke,Figs. 5 and 8, and in so doing forces the cartridge or detonator f alongthe carrier by its engaging the end e of the bar (1, and so through theopen end 6 thereof, with the exception of a short length f of saidcartridge, which is frictionally held. The carrier or projector e is nowmoved forward, Fig. 6, keeping the succeeding detonator out of the wayuntil it is free to fall into the slot a the continued movement of thecarrier through opening I) of standard I) shutting off the remainingcartridges by reason of its full circumference coming opposite theopening 9 of the magazine. On the completion of the stroke the detonatorf is placed across the rail 9', where it remains until exploded by thewheel is of the passing engine or train, (or till it is withdrawn.) Onthe next rearward movement of the carrier the unexploded detonator stillcarried therein strikes against the end 0 of the rod d and forciblyejects by its engagement therewith the exploded detonator, Fig. 5, atsametime said unexploded detonator in its turn becomes held in the openend e of the carrier e, the amount of movement of said carrier 0 beinglimited in either direction by the stops (2*, (see Figs. 5, 6, and 8,)these operations being continued as long as required. -To insure thecartridges or detonators always fitting in the magazine in their properposition, the forward end f 2 (see Fig. 10) thereof is rounded, so as tofit in a correspondingly-shaped groove g in the magazine, Fig. 10, theother end f 3 of detonator being fiat and fitting in a similar flattenedgroove 9".

When the apparatus is not in use, the magazine is removed and cover hbolted down or secured in any other suitable manner in its place, and aslide h*, Fig. 1, (shown in dotted line,) provided with an openingthrough which the operating-lever or the like projects, is drawn downand secured, covering up the opening it in the casing h, eifectuallprotecting against wet or being tampere with.

Having now described my invention, what I claim as new, and desire tosecure by Let: ters Patent of the United States, is j 1. In a railwaysignaling apparatus, a supporting-stand having a plurality of guidebars,a magazine for cartridges supported upon the stand, and having a bottomdelivery-opening, and a reciprocating tubular carrier supported by thesaid guide-bars and having a top receiving-opening and an endholding-opening for the cartridges.

2. In a railway signaling apparatus, the combination with the magazinehaving a bottom deliveryopening for cartridges, of ahorizontally-arranged bar, and a carrier-tube sliding on said bar andhaving a top receiving-opening and an end holding-opening for thecartridges, the movement of the carrier upon the bar in one directionproviding for the ejection of a spent cartridge.

3. In a railway signaling apparatus, a st and having oppositely-arrangedguide-bars and a centrally-arranged ejector-bar, a magazine detachablymounted upon the guidebar at one end of the stand, and a reciprocalcarrier-tube having a sliding engagement with the guide-rods and workingdirectly over the ejector-bar, said carrier-tube having a topreceiving-opening for the cartridges and an end holding-opening.

In'testimony whereof I have afiixed my signature in presence of twowitnesses.

JOHN PARKER.
